Raveneau does use oak in their winemaking process. However, it is important to note that the use of oak at Raveneau is quite unique and distinct from many other wineries.
The fermentation of the wines takes place largely in cuve, which are large stainless steel or concrete tanks. This allows for a controlled and precise fermentation process, without the influence of oak on the flavors and aromas of the wine.
After the initial fermentation, the wines undergo malolactic fermentation, which is a secondary fermentation that converts harsh malic acid into softer lactic acid. This process can take some time and occurs naturally in the wine.
Once the malolactic fermentation is complete, the wines are transferred to small oak barrels called feuillettes. These barrels are about half the size of a typical barrique, which allows for a higher ratio of wine to oak surface area. This means that the oak influence on the wine is more subtle and balanced.
The use of feuillettes is one of the key factors that contribute to the expressiveness of Raveneau's wines. The smaller barrels allow for a slower and more gradual integration of oak flavors into the wine. This results in a more nuanced and complex wine, with the oak playing a supporting role rather than overpowering the other characteristics of the wine.
It is also worth mentioning that Raveneau's use of oak is not excessive or dominant. The wines are aged in the feuillettes for about a year, which is a relatively short period compared to some other wineries. This ensures that the oak flavors and aromas do not overpower the natural fruit and mineral characteristics of the wine.
In my personal experience, I have had the pleasure of tasting Raveneau wines that have been aged in oak. The oak influence was indeed present, but it was beautifully integrated and added complexity to the wine without overwhelming it. The wines had a distinct elegance and finesse, with a perfect balance between fruit, acidity, and oak.
While Raveneau does use oak in their winemaking process, it is done in a careful and precise manner. The use of feuillettes and the relatively short aging period allow for a subtle and balanced oak influence, resulting in wines that are expressive, complex, and true to their terroir.
